CORPORATION OF, CONNECTICUT v 1 V VEHICL P G jAB lW 5 Application filedMarch 10, 1925. eaai m14 95,

Our invention relates to a bearing for a vehicle spring andparticularly'to an anti-- friction bearing for the hinge end of aspring..It is an object of the invention to provide a serviceable anti-frictionbearingfor the hinge end of a spring without materially changing thedesign of a conventional spring 7 and without unduly weakening thevehicle frame. t

It is a further object to provide a simple form of anti-friction springhearing which will be cheap to manufacture, serviceable in use, and easyto assemble. Other minor objects will appear as the specificationproceeds.

In the drawings, which showfor illustrative purposes only, a preferredform of the invention: 7

Figure 1 is an end view of part of a vehicle frame and spring .connectedtogether by one form of our invention, parts being shown in section;

Figure 2 isa side viewof parts shown in Figure 1, one-half of a dust capbeing cut away to expose the interior. V

In said drawings, 5 indicates a part of a vehicle frame, while 6indicates an end of a conventional form of vehicle spring. The springand frame are ordinarily hinged to each other and our invention affordsanimproved, simple anti-friction hinge for that In the form shown, theframe 5 is of channel formation, the legs of the channel beingdesignated 67. The frame is pm vided with aligned apertures therethroughas indicated at 8-8. On the outside of-the frame adjacent each'apertureis a bearing member which, in the form shown, .18 a bears ing cup 9 ofhardened metal such as steel,

having'a rearwardly extending boss-10, fit ting in the apertures in theframe for positioning the same. No means has been dis closed forsecuring the cup and frame di-i rectly. toeach other, but it is, ofcourse,"to be understood that these two members may be held to eachother if desired. 7 The cup 9 preferably has a substantialbearingsurfaceon the outside of the frame and the boss 10 fitting in theaperture 8 serves to position the cup onthe frameand overthe aperture."

l l'is secured-in the spring i eye 12 and thejends of thepin ll-project.

through the. aperture 8 and aperture ,1?) in .the boss-.10.; on; theouter end of each pin end is a bearing memberor raceway 1a which, in theform shown, is in. the form of a cone complementary to the bearing cup9,. The

in any suitablemannerand we have shown .the'same as screw threaded ontothe, end. of

the pin and a lock nut or the like-15 may be employed for holding therace ring 14 in any";

desired position of adjustment. V

F 16-46 indicate bearing members s thatthe bearing is an'angularthrustbearing which takes both-radial and thrust loads.

Inorderto exclude dust .andwaterifrom laterally beyond the edge thereofand bearing ring lmay be secured ongthe shaft the'bearing membersandadjacent parts, we r may employ-a cover or cap 17 extending over thebearing parts and in the form shown this cap is "threaded onto thebearing member 9.

It will be seen that the Jdia1neter of the circle enclosing the bearingmembersis larger than the diameter of the aperturein the frame. Suchproportioning permits us to space the ring of balls radially outwardlyat a suflicient fdistance to secure a well-proportloned bearing without,however, requiring an unduly large aperture in the frame, so

that, while wesecure aproperly proportioned bearing, the frame 5 is notunduly weakened and infactthe aperture 8 need be only as large,orsperhaps slightly larger, than the aperture ordinarily foundin theframe in the ordinary pin hinge connection.

"We have described and show'nin detail-the 1 bearing atQonly one side ofthe frame, but it willbe understood that the bearing at the, oppositeside may be, and preferably is, a

V duplicate ofthat just described. The weight.

of the vehicle will be'supported from'the spring through. theanti-friction members.

. Whilethe invention has beendescribed in j some detail, we do not wishto be strictly limited'to the form shown, since changes may.

be made Within the scope of the invention,- as defined in the appendedclaims.
